Talosaga

Lua-vaega pipiʻi tatau ona faʻaaogaina i totonu o le applicaable vaitaimi pe a maeʻa tuʻu i RE. O le umi o le vaitaimi talafeagai e le gata e fesoʻotaʻi ma le polymer mea o le pipiʻi, ae faʻapea foi ma isi vaega talafeagai (pei o le resin, antioxygen, plasticizer, solvent, ma isi. Pe a latalata i le vaitaimi talafeagai, masani ai ni nai itula poʻo se tasi aso faigaluega, pipiʻi Ua atili ai ona faigata ona faʻagaioia, ma e vave ona tulaʻi mai le viscosity mulimuli ane, ua avea ma jelly le mafai ona toe faʻafoʻi. 100 lelei pipiʻi, Hydroxyl polyurethane (Polyurethane account mo le lata i le 20%), RE fualaʻau 4-7. , O lo matou RE e faia 4-7.
